A Step-by-Step Guide to Pruning and Shaping Young Tropical Fruit Trees
2015Co-Authors: Jeff Wasielewski, John Mclaughlin, Jonathan H. CraneAbstract:Early formative pruning of Tropical and subTropical Fruit trees is important not only for ease of future size control, but to simplify maintenance and maximize productivity. Key steps involve developing trees with a canopy that is fairly low to the ground and comprised of three to four well placed co-dominant leaders. Secondary and tertiary lateral branching should be encouraged to increase the Fruit bearing potential of the tree. Tropical Fruit trees differ in growth habits and this must be taken into account as to when and how a particular species or cultivar is pruned.

Responses of SubTropical and Tropical Fruit Trees to Flooding in Calcareous Soil
Hortscience, 2006Co-Authors: Bruce Schaffer, Frederick S. Davies, Jonathan H. CraneAbstract:The effects of fl ooding calcareous soil on physiology and growth have been studied for several subTropical and Tropical Fruit crops including avocado (Persea americana Mill.), mango (Mangifera indica L.), carambola (Averrhoa carambola L.), and several Annona species. In calcareous soils that have a high pH, short-term fl ooding can actually be benefi cial to subTropical and Tropical Fruit crops by increasing the solubility of particle-bound nutrient elements such as Fe, Mn and Mg due to fl ooding-induced decreases in soil pH. Additionally, fl ooding reduces the redox potential in the soil, resulting in Fe being reduced from Fe 3+ to Fe 2+ , which is the cation metabolized by plants. As with other woody perennial crops, one of the early physiological responses of subTropical and Tropical Fruit trees to fl ooding is a decrease in stomatal conductance and net CO 2 assimilation. If the fl ooding period is prolonged, lack of O 2 (anoxia) in the soil results in a reduction of root and shoot growth, wilting, decreased nutrient uptake and eventual death. The fl ooding duration required to cause tree mortality varies among species, among cultivars within species, and with environmental conditions, particularly temperature. Several Tropical and subTropical Fruit crops have anatomical or morphological adaptations to tolerate prolonged fl ooding, such as development of hypertrophied stem lenticels, adventitious rooting or formation of porous aerenchyma tissue. For grafted trees, fl ooding-tolerance is conferred by the rootstock and not the scion. Therefore there is a possibility to increase fl ood tolerance of subTropical and Tropical Fruit crops by identifying or developing fl ood-tolerant rootstocks.

533 Monitoring Soil Water Content in Tropical Fruit Orchards in Southern Florida with Multi-sensor Capacitance Probes and Tensiometers
Hortscience, 2000Co-Authors: Roberto Núñez-elisea, Mongi Zekri, Bruce Schaffer, Stephen K. O'hair, Jonathan H. CraneAbstract:Tropical Fruit trees in southern Florida are grown in porous, oolitic limestone soil that has very low organic matter content and water-holding capacity. Thus, trees require frequent irrigation during dry periods. In these soils, a quantitative basis for monitoring soil water content to determine when and how much to irrigate has been lacking. Multi-sensor capacitance probes (EnviroSCAN™, Sentek, Australia) were installed in commercial carambola, lime, and avocado orchards to continuously monitor changes in soil water content at depths of 10, 20, 30, and 50 cm. Eight probes were installed per orchard. Volumetric soil water content was recorded at 15-min intervals with a solar-powered datalogger. Results were downloaded to a laptop computer twice a week. Monitoring the rate of soil water depletion (evapotranspiration) allowed irrigation before the onset of water stress. The time at which soil reached field capacity could be determined after each irrigation (or rain) event. Soil water tension was recorded periodically using low-tension (0–40 cbars) tensiometers placed adjacent to selected capacitance probes at 10- and 30-cm depths. Soil water tension was better correlated with volumetric soil water content at a 10-cm depth than at 30-cm depth. Using multi-sensor capacitance probes is a highly accurate, although relatively expensive, method of monitoring soil water content for scheduling irrigation in Tropical Fruit orchards. Whereas tensiometers require periodic maintenance, the multi-sensor capacitance probe system has been virtually maintenance free. The correlation between soil water content and soil water tension obtained in situ indicates that tensiometers are a less precise, but considerably cheaper, alternative for scheduling irrigation in Tropical Fruit orchards in southern Florida.

Evapotranspiration Measurement and Irrigation Scheduling for Several Tropical Fruit Crops Using the EnviroScan System
Hortscience, 1998Co-Authors: Mongi Zekri, Roberto Núñez-elisea, Bruce Schaffer, Stephen K. O'hair, Jonathan H. CraneAbstract:In southern Florida, most Tropical Fruit crops between Biscayne and Everglades National Parks are irrigated at rates and frequencies based on experience and observations of tree growth and Fruit yield rather than on reliable quantitative information of actual water use. This approach suggests that irrigation rates may be excessive and could lead to leaching of agricultural chemicals into the groundwater in this environmentally sensitive area. Therefore, a study is being conducted to increase water use efficiency and optimize irrigation by accurately scheduling irrigation using a very effective management tool (EnviroScan, Sentek Environmental Innovations, Pty., Kent, Australia) that continuously monitors soil water content with highly accurate capacitance multi-sensor probes installed at several depths within the soil profile. The system measures crop water use by monitoring soil water depletion rates and allows the maintenance of soil water content within the optimum range (below field capacity and well above the onset of plant water stress). The study is being conducted in growers' orchards with three Tropical Fruit crops (avocado, carambola, and `Tahiti' lime) to facilitate rapid adoption and utilization of research results.

European market environment for selected Latin American Tropical Fruit species
Acta Horticulturae, 2013Co-Authors: Sara Sabbe, Patrick Van Damme, Wim VerbekeAbstract:Numerous Tropical Fruit species are commercially restricted to their production areas and only sold on local, regional and national markets. They are virtually unknown to temperate area consumers. However, growing demand in Europe for natural, nutritious and healthy products and new flavours offers interesting perspectives for creating new and international market outlets for novel Tropical Fruit juices. Five Tropical Fruit species from Latin America (i.e., acai (Euterpe oleracea Mart.), camu camu (Myrciaria dubia (Kunth) McVaugh), cashew apple (Anacardium occidentale L.) from Brazil, and naranjilla (Solanum quitoense Lam.) and tree tomato (Solanum betaceum Cav.) from Ecuador) were selected as case species for a SWOT analysis. Through desk research, field visits and expert interviews, opportunities, threats, strengths and weaknesses related to the Fruits' potential use in the European Fruit juice industry were investigated. Findings indicate that Tropical Fruit species with outstanding nutritional values and proven health benefits have substantial market potential. Lack of advanced knowledge about production and processing issues, inconsistent Fruit quality, irregular and insufficient Fruit supply, and unfamiliarity with the respective Fruits and their sensory characteristics by European consumers are the main challenges that have to be dealt with when envisaging product development for the European market.

Confirmation/disconfirmation of consumers’ expectations about fresh and processed Tropical Fruit products
International Journal of Food Science and Technology, 2009Co-Authors: Sara Sabbe, Wim Verbeke, Patrick Van DammeAbstract:Summary This study investigates Tropical Fruit acceptance in terms of confirmation or disconfirmation of consumers’ general expectations. Consumers evaluated multiple product attributes before and after tasting five fresh and five processed Tropical Fruit products. Consumers’ general expectations were confirmed after tasting persimmon (Diospyros kaki L.) and cashew apple juice (Anacardium occidentale L.). Positive disconfirmation occurred after the consumption of cherimoya (Annona cherimola Mill.) and berrycactus jam (Myrtillocactus spp.) whereas expectations were negatively disconfirmed after consuming dragon Fruit (Hylocereus spp.), mangosteen (Garcinia mangostana L.), tree tomato (Solanum betaceum Cav.), acai juice (Euterpe oleracea Mart.), baobob juice (Adansonia digitata L.) and tamarind jam (Tamarindus indica L.). Sensory experiences are demonstrated to greatly influence the acceptance and purchasing intention of Tropical Fruits and their products, as well as to affect consumers’ perceptions about the product’s health and nutritional benefits, in particular in cases where negative taste disconfirmation occurred.

European market environment for Latin American Tropical Fruit species
2008Co-Authors: Sara Sabbe, Wim Verbeke, Patrick Van DammeAbstract:Numerous Tropical Fruit species are commercially restricted to their production areas and only sold on local and regional markets. They are virtually unknown to temperate area consumers. However, growing demand in Europe for natural and healthy products and new flavours offers interesting perspectives for creating new and international market outlets for these products. Nine Tropical Fruit species from Latin America, i.e. Andean blackberry (Rubus spp.), tree tomato (Cyphomandra betacea C. Martius ex Sendtner), dragon Fruit (Hylocereus spp.), berrycactus (Myrtillocactus spp.), acai (Euterpe oleracea Mart.), cashew apple (Anacardium occidentale L.), naranjilla (Solanum quitoense Lam.), peach palm Fruit (Bactris gasipaes Kunth) and camu camu (Myrciaria dubia (Kunth) McVaugh), were selected as case species for a SWOT analysis. Their international market potential as well as the main problems and perspectives related to their commercialization were investigated based on document analysis and in situ consultations with different actors of the predetermined production and supply chains. Findings indicate that those species with outstanding nutritional values and health benefits have substantial market potential. Lack of knowledge about production and processing issues, irregularity of supply, unfamiliarity with the Fruits and their sensory characteristics by European consumers are the main challenges to cope with when envisaging product development for the European market.
